Benefits of technology

The patent describes a technique for treating heart tissue using ultrasound energy. A reflection-facilitation element is placed at a nearby site to enhance the treatment. The ultrasound energy is reflected from the element back through the heart tissue, resulting in more energy directed at the treatment site and increasing the depth and homogeneity of the lesion. The technique also involves measuring the time of flight of the ultrasound energy and controlling the treatment based on this information. This can help to account for the behavior of atrial contractions and other factors that may affect treatment results. Overall, this technique provides a faster and more effective way to create transmural lesions in heart tissue.

Problems solved by technology

Atrial fibrillation disrupts efficient beating of the heart and may result in blood clotting in the atrium leading to serious medical conditions such as strokes.

Embodiment Construction

[0092]Reference is made to FIGS. 1A-B, which are schematic illustrations of an ultrasound ablation system 10, in accordance with some applications of the present invention. Ablation system 10 comprises an ultrasound tool 20 and a reflection-facilitation element 12, which, as described hereinbelow, provides a reflective region. Ultrasound tool 20 comprises at least one ultrasound transducer 40. Tool 20 typically further comprises a catheter 22, for facilitating advancement of the tool into a chamber of a heart of a subject. Tool 20 also may comprise a proximal shaft 24, which may house a distal shaft 23, which comprises a proximal portion 31, a distal portion 32, and a hinge 44. The hinge connects the proximal and distal portions, and facilitates rotation of different elements of tool 20. (In this context, in the specification and in the claims, “proximal” means closer to the orifice through which the tool is originally placed into the body, and “distal” means further from this orifi...

Abstract

Apparatus is provided that includes an ultrasound ablation system, which includes a reflection-facilitation element, configured to be placed at an extramyocardial site of a subject, and to provide an extramyocardial reflective region. The system further includes an ultrasound tool, which comprises at least one ultrasound transducer configured to be positioned within a heart chamber of the subject, and to ablate myocardial tissue by applying ultrasound energy to the myocardial tissue such that at least a portion of the transmitted energy is reflected by the reflective region onto the myocardial tissue. Other embodiments are also described.

Description

FIELD OF THE APPLICATION[0001]Embodiments of the present invention relate generally to treatment of tissue by application of energy thereto, and particularly to ablation of cardiac tissue by application of ultrasound energy.BACKGROUND OF THE APPLICATION[0002]Atrial fibrillation is a common cardiac arrhythmia involving the atria of the heart. During atrial fibrillation, the atria beat irregularly and out of coordination with the ventricles of the heart. Atrial fibrillation disrupts efficient beating of the heart and may result in blood clotting in the atrium leading to serious medical conditions such as strokes.[0003]Atrial fibrillation is generally caused by abnormal electrical activity in the heart. During atrial fibrillation, electrical discharges may be generated by parts of the atria which do not normally generate electrical discharges, such as pulmonary vein ostia in the atrium. Pulmonary vein isolation is a common medical procedure for treatment of atrial fibrillation.[0004]Ab...
